You will have no tax liability if:
1. For 2017; Your non social security income is less than $20,800 ($22,350 if one of you is 65+ or $23,900 if both are 65+) . For 2018, the numbers are $24,000 - 25,300 -26,600.
AND
2. Your non SS income plus half of your SS income is less than $32,000.
BOTH conditions must be met. If only is one is met, you will owe and are required to file a return.
With $60,000 total; it's unlikely you meet both conditions.
What is the breakdown of the $60,000 gross? That is. how much is SS and how much is pension? Any other income?
For husband and spouse, SS is $42000, State of Ca. pension is $18000. No private income
18,000 + 21,000 (half of 42000) = 39,000 which is more than the $32,000 threshold, so you will owe a small amount of tax (about $150), unless you itemize deductions. Either way, you are required to file a return.

TAX ON SOCIAL SECURITY
Up to 85% of your Social Security benefits can be taxable. There is no age limit for having to pay taxes on Social Security benefits if you have other sources of income along with the SS benefits. When you have other income such as earnings from continuing to work, investment income, pensions, etc. up to 85% of your SS can be taxable.
What confuses people about this is that before you reach full retirement age, if you continue working while drawing SS, your benefits can be reduced if you earn over a certain limit. (For 2017 that limit is $16,920) After full retirement age, no matter how much you continue to earn, your benefits are not reduced by your earnings; your employer will still have to withhold for Social Security and Medicare.
To see how much of your Social Security was taxable, look at line 14b of your 1040A, or line 20b of your 1040
